The naturalistic fallacy is mentioned frequently by evolutionary psychologists as an erroneous way of thinking about the ethical implications of evolved behaviors. However, evolutionary psychologists are themselves confused about the naturalistic fallacy and use it inappropriately to forestall legitimate ethical discussion. We briefly review what the naturalistic fallacy is and why it is misused by evolutionary psychologists. Then we attempt to show how the ethical implications of evolved behaviors can be discussed constructively without impeding evolutionary psychological research. (...) A key is to show how ethical behaviors, in addition to unethical behaviors, can evolve by natural selection. (shrink)

The COVID-19 pandemic highlights the relevance of adequate decision making at both public health and healthcare levels. A bioethical response to the demand for medical care, supplies and access to critical care is needed. Ethically sound strategies are required for the allocation of increasingly scarce resources, such as rationing critical care beds. In this regard, it is worth mentioning the so-called ‘last bed dilemma’. In this paper, we examine this dilemma, pointing out the main criteria used to solve it and (...) argue that we cannot face these ethical issues as though they are only a dilemma. A more complex ethical view regarding the care of COVID-19 patients that is focused on proportional and ordinary treatments is required. Furthermore, discussions and forward planning are essential because deliberation becomes extremely complex during an emergency and the physicians’ sense of responsibility may be increased if it is faced only as a moral dilemma.

The defeat of the USSR and of the world system of socialism, which was of a world-wide significance, raised a key question of its underlying causes. As an answer to that question, it is shown that the defeat was by no way accidental as it was brought forth not only because of mistakes in the application of Marxism but also of significant economic and socio-political fallacies. The key is in the fallacies, which are hidden deeply inside the methodology of Marxism (...) and which therefore went unnoticed by anyone, i.e. in the violation in Marx’s Das Kapital of the requirements of a number of scientific methods that he used. Marx violated the requirements of the main method used in Das Kapital, viz. the method of ascension from the abstract to the concrete (he attributed the function of forecasting the future to that method, even though the method does not have it) as well as the methods of forecast, systems approach and hypothesis. Those methodological fallacies and distortions and their epistemological consequences provide evidence that Marxism is a result of seriously flawed beliefs and it could not avoid failure. Exposure of the above-mentioned fallacies and distortions will help broad masses of people to shed communist illusions and to avoid new social and political upheavals. (shrink)

Many engineering ethics classes and textbooks introduce theories such as utilitarianism and Kantianism (and most others draw from these theories without mentioning them explicitly). Yet using ethical theories to teach engineering ethics is not devoid of difficulty. First, their status is unclear (should one pick a single theory or use them all? does it make a difference?) Also, textbooks generally assume or fallaciously ‘prove’ that egoism (or even simply accounting for one’s interests) is wrong. Further, the drawbacks of ethical theories (...) are underestimated and the theories are also otherwise misrepresented to make them more suitable for engineering ethics as the authors construe it, viz. the ‘moral reasoning’ process. Stating in what various theories disagree would allow the students to frame the problem more productively in terms of motive–consequence or society–individual dichotomies rather than in terms of Kant–utilitarian.

This paper tries to offer a descriptive account of the normative workings of evaluative fallacy charges directed to narratives. In order to do that, I first defend the continuity and mutual dependence, as based on a dynamical conception of argument, between the ‘belief conception’ and the ‘argumentative conception’ of fallacy. Then, I construe a catalogue of ‘fallacy charges’ based on both such a continuity and the variety of counterarguments explored by the theoretical framework of Argument Dialectics. And (...) finally, I apply these ideas and distinctions in the analysis of four examples of published texts in which the charge of ‘fallacious narrative’ is issued by a discursive agent against other discursive agents’ either full-fledged narratives or narrative assumptions. The analyses confirm some of the characteristics mentioned in the catalogue as well as the argumentative nature of fallacy charges, even when the censored discourse does not exactly or explicitly contain an argument. The analyses also help understand the distinction between a rather concrete ‘linguistic’ use of the term narrative and a more abstract and elusive ‘discursive’ one, in which the difficulties of both identifying the object of censorship and the exact meaning of the fallacy charge multiply.

Paul Saka, in a recent paper, declares that we can use, mention, or quote an expression. Whether a speaker is using or mentioning an expression, on a given occasion, depends on his intentions. An exhibited expression is used, if the exhibiter intends to direct his audience’s attention to the expression’s extension. It is mentioned, if he intends to draw his audience’s attention to something associated with the exhibited token other than its extension. This includes, but is not limited to, (...) an orthographic form, a phonic form, a lexical entry, and an intension. (shrink)

In this paper we contend that the ability to engage in meta-dialog is necessary for free and exible conversation. Central to the possibility of meta-dialog is the ability to recognize and negotiate the distinction between the use and mention of a word. The paper surveys existing theoretical approaches to the use-mention distinction, and brie y describes some of our ongoing e orts to implement a system which represents the use-mention distinction in the service of simple meta-dialog.

It is argued that the use/mention distinction, if it is to be a clear-cut one, cannot have the significance that it is usually thought to have. For that significance attaches to the distinction between employing an expression in order to draw attention to, or to talk about, some aspect of the world, as determined by the expression’s meaning, and employing it in order to draw attention to, or to talk about, the expression itself—and this distinction is not a clear-cut (...) one. In the final section of the essay this argument is extended to cast doubt on a rather glib appeal to the use/mention distinction that is frequently made in the philosophy of language. (shrink)

There are many fallacious arguments in the dialogues of Plato.

Plato is thus able to expose them for what they are, to clear (...) away possible lines of attack upon his own position, and even to show that when the proper correction is applied his own views receive support.

Quote marks, I claim, serve to select from the multiple ostensions that are produced whenever any expression is uttered; they act to constrain pragmatic ambiguity or indeterminacy. My argument proceeds by showing that the proffered account fares better than its rivals-the Name, Description, Demonstrative, and Identity Theories. Along the way I shall need to explain and emphasize that quoting is not simply the same thing as mentioning. Quoting, but not mentioning, relies on the use of conventional devices.

The use-mention distinction is considered as a fundamental concept in the philosophy of language. So it goes without doubt that a comprehensive theory of language has to account for this distinction. In this paper I explore what it means to account for such a distinction and I argue that the main ideas of contextualist theories of language are in conflict with the distinction in question.

Burt's argument relies on a motte-and-bailey fallacy. Burt aims to argue against the value of genetics for social science; instead she argues against certain interpretations of a specific kind of genetics tool, polygenic scores (PGSs). The limitations, previously identified by behavioural geneticists including ourselves, do not negate the value of PGSs, let alone genetics in general, for social science.

In this commentary on Chalmers’s work on the meta-problem of consciousness, I defend an approach to the meta-problem that Chalmers finds unpromising (i.e., what Chalmers has called the “use-mention fallacy” strategy.) The core of this strategy is the idea that thinking about consciousness requires a special mode of thought that activates phenomenal consciousness itself, which then facilitates a (mistaken) intuition that a first-person thought of consciousness and a third-person thought of a brain state cannot refer to the same (...) thing. Chalmers considers this strategy as offering a diagnosis in terms of the “use-mention fallacy” and dismisses it quickly. However, close examination shows that the strategy is not about a use-mention confusion. Also, a revision to this strategy can provide an account that withstands counterexamples and connects with many ideas that may lead to a solution to the meta-problem. (shrink)

According to quotational theory, indirect ascriptions of propositional attitudes should be analyzed as direct ascriptions of attitudes towards natural-language sentences specified by quotations. A famous objection to this theory is Church's translation argument. In the literature several objections to the translation argument have been raised, which in this paper are shown to be unsuccessful. This paper offers a new objection. We argue against Church's presupposition that quoted expressions, since they are mentioned, cannot be translated. In many contexts quoted expressions are (...) used and mentioned simultaneously, and the quotational analysis of propositional-attitude ascriptions is such a context. Hence the translation argument is unsound. (shrink)

Connecting research and production, art research represents a breaking of the barrier between creation and academia. However, there is also a contradiction contained in this kind of research deriving from its methods, since the process of art-based practice must, by its very nature, involve the subjectivity of the artist. I use my own studies as the research object to discuss this issue, and this article presents the problems I encountered during my artistic practice and research of ambiguous roles. This paper (...) has two main points of focus. First, I explore how the fallacy of self-referentiality is presented in paintings and films, and, second, I draw on my short film practice during my master’s study period to explain how the shots present a continuum in relation to the “absent one” and produce interface effects. However, the second point is not necessarily the result of the first one. This kind of connection and contradiction between practice and cognition in the process of art research is that I will analyse and discuss here. (shrink)

Imagine my surprise at discovering - tucked inside the cover of a first edition Alice in Wonderland – an unknown dialogue written by Lewis Carroll himself! It was scribbled on the back of a napkin, punctuated by Carroll’s tell-tale signature, and seems to have been written hastily. Carroll is known among laypersons as an absurdist, but he’s esteemed among formal thinkers as impressively logical. You can probably then imagine my further surprise at discovering various fallacies and confusions in the dialogue! (...) I counted equivocations over use/mention, identity/predication, measurements, and lexical/material parthood, but I’m sure there are more hiding. -/- If you share my interest in untangling these errors, I’ve copied Carroll’s dialogue below. I’ve found the task best pursued with help, whether students, interns, sisters, tarot readers, etc. As you’ll see, I’ve divided the dialogue into five sections, of varying difficulties. I recommend dividing helpers accordingly, assigning one section per group, then directing each to identify both good and bad reasoning in the section. After some time, groups should pass their discoveries to other groups for scrutiny. For example, if group 1 examined section 1, they’d pass their discoveries to group 2 who then checks group 1’s work against section 1. Proceed until each group has examined each section and – hopefully – you’ll find all the errors. Happy hunting! (shrink)

In lieu of an abstract, here is a brief excerpt of the content:RUSSELLS ARGUMENT AGAINST FREGE'S SENSE-REFERENCE DISTINCTION PAWEL TURNAu Philosophy I Jagiellonian University Cracow, Poland I n "On Denoting"l Russell argued that Frege's theory of sense and reference was an "inextricable tangle", but, ironically, many readers found the argument even more knotry. In an effort to make sense of it, commentators were often driven to attribute to Russell quite obvious and simple fallacies. A different approach was taken by Peter (...) Geach, who suggested that Russell's argument could be given a consistent reading if it were construed as arguing, not against Frege's theory, but against Russell's own earlier theory, which he put forward in The Principles of Mathematics. It is not an implausible hypothesis, considering how prone Russell was to misrepresent' other philosophers' views and read his own powerful ideas into their writings. In order to justifY Geach's hypothesis properly, one would have to show the crucial difference between Russell's and Frege's theories that made only one of them susceptible to the attack in "On Denoting ". Russell explicitly considered the two theories to be "very nearly the same"; this self-interpretation would have to be questioned. Geach's hypothesis would be further strengthened by providing an actual exegesis of the "On Denoting" argument as directed against The Principles ofMathematics theory. In this paper 1 will try to accomplish both of these tasks. Russell is often accused of confusing use and mention. The accusation is not fair, however. It is true that he does not insist on this distinction; he does not employ it extensively. But he is certainly Russell's Argument against Frege's Distinction 53 aware of it; he simply does not think that it is an important logical distinction. Today this view may seem almost incomprehensible, but that only shows the strength of Frege's influence on our ideas. There are two striking symptoms of Russell's lack of concern for the use-mention distinction: firstly, he does not observe the convention which says that putting an expression in quotation marks produces a name of that expression; secondly, he does not feel any need to employ the pair of terms "sentence" and "proposition", but contents himself with the latter only. The claim about Russell's use of inverted commas needs to be proved; I will come to that later. Russell's assertions are often ambiguous between use and mention of expressions. For example, he asserts that "propositions do not contain words" (PaM, p. 47). However, a few pages later, he speaks of propositions that contain the phrase "any number" (p. 53). If this is not to be self-contradictory, then either the term "proposition" must sometimes signifY a linguistic expression, or the term "phrase" must sometimes be understood without implying that a phrase consists of words. This ambiguity is openly admitted in a later article, where he writes: [we shall be concerned with] the distinction between verbs and substantives, or, more correctly, between the objects denoted by verbs and the objects denoted by substantives. Since this more correct expression is long and cumbrous, I shall generally use the shorter expression to mean the same thing. Thus, when I speak of verbs, I mean the object denoted by verbs, and similarly for substantives.2. Russell's attitude towards the distinction between use and mention is not unjustified. It has its reason in his view oflanguage and the subject -matter of logic. In Russell's view, the subject-matter of logic has nothing to do with language. Words, both spoken and written, are entirely outside its realm. Logic, just as other sciences (except linguistics ), is concerned with the entities indicated by words, and not with words themselves. Even the relation of indicating, which holds between words and things in the world, is of no interest to it: "mean1 In Lf(, pp. 39-56. russ.lI: the Journal of the Bertrand Russell Archives McMaster Univecsity Library Press n.s. 11 (summer 1991): 51- 66 ISSN 0036-o16~ 2 B.

Quotation exhibits characteristics of both use and mention. I argue against the recently popular pragmatic reductions of quotation to mere language use (Recanati 2001), and in favor of a truly hybrid account synthesizing and extending Potts (2007) and Geurts and Maier (2005), using a mention logic and a dynamic semantics with presupposition to establish a context-driven meaning shift. The main advantages are an account of error neutralization and shifted indexicality under quotation. The current paper addresses the problematic data (...) involving quoted non-constituents.

The distinction between the use of a linguistic item and its mention is widely recognized as one of the basic tenets of contemporary philosophy of language. A common misconception of what is entailed by this distinction is that when an expression is being mentioned it is thereby not being used in its ordinary use. In this work I explore the workings of this false assumption and argue against it by rehabilitating linguistic reflexivity as an everyday mode of expression. By (...) showing that our ordinary means for mentioning linguistic items are highly sensitive to context, I argue that expressions are often used and mentioned simultaneously, a fact that has far-reaching consequences also outside the philosophy of language proper. ;The first chapter, "Mentionability in Frege and Russell", is devoted to identifying common strands in the works of these two pioneers of the analytic tradition as providing a deep source for the idea that mentioned expressions, by the very fact of being mentioned, are not simultaneously being used. In the second and third chapters I explore different manifestations of this notion in theories of quotation. In the second chapter, "Ideal Quotation", I discuss Sellars' theory and locate it at the locus of a large epistemological concern to distinguish sharply between an empirical aspect of language and a formal aspect. Whatever the merits of such a theory are for Sellars' specific theoretical purposes, it leaves little room for considering quotation as an actual, everyday means for mentioning expressions. The third chapter, "Quotation and the Mixing of Use and Mention", is devoted to an examination of contemporary attempts to account for our actual quoting practices. I argue that of the five theories of quotation currently available only a recent version of the demonstrative theory can accommodate the simultaneity of use and mention. The fourth chapter, "Norms and Mention", applies the results of the preceding chapters to a particular vexing problem which lies at the heart of the intersection between language and normativity---the threat of a normative skepticism inspired by Lewis Carroll's parable about licensing inferences in "What the Tortoise Said to Achilles".

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to 0.025 (...) when testing H1,1 and H1,2, find a significant result for H1,1 (p < 0.025) and not for H1,2 (p > .0.025), and so claim support for H1,1 and not for H1,2. However, these separate individual inferences do not require an alpha adjustment. Only a statistical inference about the union alternative hypothesis “H1,1 or H1,2” requires an alpha adjustment because it is based on “at least one” significant result among the two tests, and so it refers to the familywise error rate. Hence, an inconsistent correction occurs when a researcher corrects their alpha level during multiple testing but does not make an inference about a union alternative hypothesis. In the present article, I discuss this inconsistent correction problem, including its reduction in statistical power for tests of individual hypotheses and its potential causes vis-à-vis error rate confusions and the alpha adjustment ritual. I also provide three illustrations of inconsistent corrections from recent psychology studies. I conclude that inconsistent corrections represent a symptom of statisticism, and I call for a more nuanced inference-based approach to multiple testing corrections. (shrink)

Often implicit in visual display design and development is a gold standard of photorealism. By approximating direct perception, photorealism appeals to users and designers by being both attractive and apparently effortless. The vexing result from numerous performance evaluations, though, is that increasing realism often impairs performance. Smallman and St. John (2005) labeled misplaced faith in realistic information display Naïve Realism and theorized it resulted from a triplet of folk fallacies about perception. Here, we illustrate issues associated with the wider trend (...) towards realism by focusing on a specific current trend for high-fidelity perspective view (3D) geospatial displays. In two experiments, we validated Naïve Realism for different terrain understanding tasks, explored whether certain individuals are particularly prone to Naïve Realism, and determined the ability of task feedback to mitigate Naïve Realism. Performance was measured for laying and judging a concealed route across realistic terrain shown in different display formats. Task feedback was either implicit, in Experiment 1, or explicit in Experiment 2. Prospective and retrospective intuitions about the best display formats for the tasks were recorded and then related to task performance and participant spatial ability. Participants generally intuited they would perform tasks better with more realism than they actually required. For example, counter to intuitions, lowering fidelity of the terrain display revealed the gross scene layout needed to lay a well-concealed route. Individuals of high spatial ability calibrated their intuitions with only implicit task feedback, whereas those of low spatial ability required salient, explicit feedback to calibrate their intuitions about display realism. Results are discussed in the wider context of applying perceptual science to display design, and combating folk fallacies. (shrink)

In recent years considerable attention has been focused on the question whether Plato ever uses arguments he knows to be sophistical, especially whether he puts such arguments into the mouth of Socrates. Though differing views have been held, at the present time the majority of scholars seem to believe that Plato does not. Though I disagree with this position, I will not attack it directly in this paper. Instead I will discuss what I take to be an important preliminary matter, (...) establishing criteria that can be employed in order to assess the claim that one of Plato's characters does or does not argue sophistically. Since the case of Socrates is by far the most important, I will limit discussion here to the question whether Socrates ever uses sophistry. (shrink)

Quotation is employed in mentioning linguistic items with varying degrees of specificity depending upon context, occasionally in the service of multiple purposes. It is also often employed in cases where the mentioned items are simultaneously being used in their ordinary roles. I argue that against appearances to the contrary, the recently proposed formal disambiguation approach to quotation fails to account for this quotational mixing of use and mention. I further argue that, given the ubiquity of the mixing in question, (...) the demonstrative theory, in its ability to accommodate such cases, fares better than its rivals. (shrink)

Several of the so-called “fallacies” in Aristotle are not in fact mistaken inference-types, but mistakes or breaches of rules in the questioning games which were practiced in the Academy and in the Lyceum. Hence the entire Aristotelian theory of “fallacies” ought to be studied by reference to the author's interrogative model of inquiry, based on his theory of questions and answers, rather than as a part of the theory of inference. Most of the “fallacies” mentioned by Aristotle can in fact (...) be diagnosed by means of the interrogative model, including petitio principii, multiple questions, “babbling’, etc., and so can Aristotle's alleged anticipation of the fallacy of argumentum ad hominem. The entire Aristotelian conception of inquiry is an interrogative one. Deductive conclusions caught Aristotle's attention in the form of answers that every rational interlocutor must give, assuming only his own earlier answers. Several features of Aristotle's methodology can be understood by means of the interrogative model, including the role of endoxa in it. Theoretically, there is also considerable leeway as to whether “fallacies” are conceived of as mistakes in questioning or as breaches of the rules that govern questioning games. (shrink)

The fallacy of ignoring qualifications, or secundum quid et simpliciter, is a deceptive strategy that is pervasive in argumentative dialogues, discourses, and discussions. It consists in misrepresenting an utterance so that its meaning is broadened, narrowed, or simply modified to pursue different goals, such as drawing a specific conclusion, attacking the interlocutor, or generating humorous reactions. The “secundum quid” was described by Aristotle as an interpretative manipulative strategy, based on the contrast between the “proper” sense of a statement and (...) its meaning taken absolutely or in a certain respect. However, how can an “unqualified” statement have a proper meaning different from the qualified one, and vice versa? This “linguistic” fallacy brings to light a complex relationship between pragmatics, argumentation, and interpretation. The secundum quid is described in this paper as a manipulative argument, whose deceptive effect lies in its pragmatic dimension. This fallacy is analyzed as a strategy of decontextualization lying at the interface between pragmatics and argumentation and consisting of the unwarranted passage from an ut-terance to its semantic representation. By ignoring the available evidence and the presumptive interpretation of a statement, the speaker places it in a different context or suppresses textual and contextual evidence to infer a specific meaning different from the presumable one.

This chapter focuses on one of the common fallacies in Western philosophy, 'intentional fallacy (IF)'. The IF is an odd kind of fallacy. Rather than being a fallacy focused on logic and argumentation, it is a fallacy that focuses on art, relating to how we judge art and engage in literary criticism. The IF focuses on the fact that we often think that there is one right interpretation of a work of art. According to David Fenner, (...) the IF “states that we do not need to know, nor can we on most occasions, what was in the mind of the artist in order to interpret the art work”. So, it seems unreasonable to use the artist's intention as the most important way to understand a work of art as the artist's intention is often unavailable. The IF is an error in art interpretation that causes us to realize important things about art. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy: the moralistic fallacy. The moralistic fallacy occurs when one concludes that something is a particular way because it should or ought to be that way. Alternatively, this fallacy occurs when one concludes that something cannot be a particular way because it should not or ought not be that way. The moralistic fallacy is often described as the reverse of the is/ought fallacy, wherein one (...) reasons fallaciously that because things are a particular way, they ought to be that way. Variations of the moralistic fallacy occur whenever any normative claim is used to justify a factual claim about the world, and so the pattern of fallacious reason central to the moralistic fallacy can also be found in legal reasoning, prudential reasoning, or reasoning regarding proper etiquette, aesthetics, humor, or appropriate emotional responses.

Fallacies are things people commit, and when they commit them they do something wrong. What kind of activities are people engaged in when they commit fallacies, and in what way are they doing something wrong? Many different things are called fallacies. The diversity of the use of the concept of a fallacy suggests that we are dealing with a family of cases not related by a common essence. However, we suggest a simple account of the nature of fallacies which (...) encompasses them all, viz., the term “fallacy” is our most general term for criticizing any general procedure used for the fixation of beliefs that has an unacceptably high tendency to generate false or unfounded beliefs, relative to that method of fixing beliefs. Very different sorts of things called fallacies are examined in the light of this account, e.g., denying the antecedent, circular arguments, so-called informal fallacies, and propositions said to be fallacies. We do not provide a theory of fallacies. Still, on our account pretty much all of those things that have been called fallacies are fallacies, and they have been called fallacies for pretty much the same reasons. (shrink)

Fallacies are the ‘ideal types of improper inference’, named only because they represent a common or seductive error. Naming them facilitates identification (reducing ‘false negatives’ in argument evaluation), but increases the risk of false positives; it is essentially a cost-effectiveness issue whether to introduce a new name. Statistical fallacies include errors of elementary experimental design, but also conceptual confusions, e.g. of cause with correlation, of association with guilt, where an illicit substitution is made. The focus here is on recent nationwide (...) efforts to replace criteria of merit with correlates of success, in the evaluation of teaching. This involves a number of mistakes, including ‘precipitate decision’, confusing the normative with the descriptive, and using minimax when optimizing or maximin is appropriate, as well as various legal and ethical blunders.
